New Comment:
Would it be possible to add a flag to the end of the function call to
specify that you want it to return the name of the previously selected
db? eg:
$old_db_name = mysql_select_db('somedb', RETURN_OLD_DBNAME);
?

True, but given that currently the only possible values the function
can return are TRUE or FALSE, it seems unlikely that anyone would
actually do that. Is there any other way to get the name of the current
db inside a function without using global?

Well, I can see.
If someone wrote
if (true === mysql_select_db( ...
it's broken (and the API has been long this way).

Would it be possible for mysql_select_db() to return the previously
selected db on success, and false (as it does already) on failure? That
would make it more useful for times when you want to use another db
temporarily, eg:
function auth() {
// choose the auth db
$old_db_name = mysql_select_db('authdb');
// ... code to authenticate a user here ...
// change back to whatever was being used before
mysql_select_db($old_db_name);
}
I can't see how adding this would break any existing scripts, either,
as the returned value would still have to be true (you can't create
databases called '' in mysql, can you?).

Peter Lowe.
